Comparative Kinetic Study Of Functionalized Carbon Nanotubes And Magnetic Biochar For Removal Of Cd2+ Ions From Wastewater

Faculty of Engineering University of Malaya

We did a comparative study between functionalized multiwall carbon nanotube (FMWCNTs), and magnetic biochar was carried out to determine the most efficient adsorbent to be employed in the Cd2+ ion removal. We optimized parameters such as agitation speed, contact time, pH and adsorbent dosage using design expert vrsion 6.08. The statistical analysis reveals that optimized condition for highest removal of Cd2+ are at pH 5.0, with dosage 1.0 g, agitation speed and contact time of 100 rpm and 90 minutes, respectively. For the initial concentration of 10mg/l, the removal efficiency of Cd2+ using FMWCNTs was 90% and and 82% of …

Climate Hawks And California's Carbon Offset Program, Ross Astoria

Ross Astoria

Abstract Two non-profit organizations composed of climate hawks are presently challenging the legality of the offset portions of California’s greenhouse gas cap-and-trade regulations. They claim that the offset protocols do not guarantee “additionality” as required by AB 32, the Global Warming Solutions Act. In this paper, I look at the general regulatory framework in which California offset projects are to be developed and argue that for the most part climate hawks ought to use the protocols to develop buy-in and disseminate expertise, two “incidental” yet indispensible aspects of successful GHG mitigation policy. The degree to which these two goals can …

Remaking The World To Save It: Applying U.S. Environmental Laws To Climate Engineering Projects, Tracy Hester

Tracy Hester

Given the high levels of greenhouse gases already in the atmosphere and the likelihood of growing emissions in the future, even aggressive limits on greenhouse gas emissions might ultimately fail to prevent dangerous climate disruptions. To prepare for this risk, some scientists have started to explore techniques that directly influence or control global and regional climatic systems to offset climate change effects. As climate engineering research expands, U.S. environmental law could become an important forum for efforts to control nascent climate engineering technologies. Federal and state agencies should start now to map out regulatory strategies and guidance for potential requests …

Optimization Of Pyrolysis Of Oil Palm Empty Fruit Bunches, Nor Kartini Binti Abu Bakar

Nor Kartini Binti Abu Bakar

In this study, pyrolysis of oil palm empty fruit bunches (EFB) was investigated using a quartz fluidizedfixed bed reactor. The effects of various pyrolysis temperatures, particle sizes and heating rates on the yields of the products were investigated. The temperature of pyrolysis and heating rate were varied in the range of 300°C-700°C and 10°C-100°C min1, respectively. The particle size was varied in the range of<90, 91-106, 107-125 and 126-250 μm. The products obtained from pyrolysis of EFB were bio-oil, char and gas. Under the experimental conditions, the maximum bio-oil yield was 42% obtained at 500°C, with a heating rate of 100°C min 1 and a particle size of 91-1 06 μm. The maximum yield of char was 42%, obtained at a pyrolysis temperature of 300°C, heating rate of 30°C min1 and particle size of 91-106 μm. Meanwhile, the optimum yield of gas was 46%, which could be achieved at a pyrolysis temperature of 700°C, heating rate of3O°C min1 and particle size of 107-125 μm.
